Smithsonian Institution Global Volcanism Network Bulletin v. 20, no. 2, February 1995 Popocatepetl (Mexico) Small ash cone observed in summit crater; plume rises 3 km Popocatepetl central Mexico 19.02N, 98.62W; summit elev. 5,465 m All times are local (= GMT - 6 hours) On the morning of 21 February at 1105, for the first time since eruptions began on 21 December 1994, Claus Siebe was able to look into the crater from a helicopter without fumes or ash impeding visibility. A small crater surrounded by a tuff cone composed of light-brown to gray silty-sandy ash occupied the site of the former lake. Judging from the color, he interpreted the loose ash to be mostly non-juvenile. A plume was emitted from a depression in the ash cone at 1115 and rose ~3 km above the crater rim. No snow has fallen in recent weeks, and all the snow and ice in the summit area was covered by a thin coat of ash.
